Yesterday my engine light came on our 2000 minivan, 3.3 engine. We got a code of P1491 indicating a radiator fan relay circuit condition. The car overheated as a result on the wife's return home from work. She turned on the heat and the overheating was abated temporarily. Where can we start to check for the problem? I checked the relays and fuses near the battery and there is no fan relay circuit. I see a blower motor relay. I also see a "rad fan" 40v fuse which looks difference from the rest of the 40's. Where is the radiator fan relay located in the mini-van? Your assistance is greatly appreciated. Ron N. Johnson.
